I try to plug 2 MCP9808 Temperature sensor on my Raspberry PI, but I think that it’s not without a GPIO Expander, right ?
Only one MCP9808 is not a problem, but 2 is impossible without an GPIO expansion ?
- (1) mcp9808 has three hardware address lines, so you can put 8 such devices on the I2C bus. (2) Reference: cdn-shop.adafruit.com/datasheets/MCP9808.pdf. – tlfong01 1 hour ago
